Yes, we tried to kill German civilians to destroy Nazi moral. NO ONE, including the Dutch and French cheered louder than the Russians. How soon these people forget. Frankly, they can go to hell.
The biggest mistake in US foreign policy? Taking part in WW1. We stay out, the Kaiser wins. No USSR, no modern France, no Hitler, no holocost, etc.
Funny, this evening I read All Quiet on the Western Front for the first time...
Had a weird feeling when the American faces arrived.
How would France be different?
Well...if we had stayed out of WW 1...the war would have come to a closure by 1918 with revolts from the soldiers from Germany, France, and England. The entire French government would have dissolved by the end of 1918 because of the impending revolt. Russia was already dissolving into communism because of Germany's release of Lenin. A peace agreement of some type would have been forged and quickly signed, and everyone would have gone back home. Hitler wouldn't have had the breeding ground to expand his party, and the Kaiser would have kept rule intact within Germany.
This is not to say that the affair is ended...I think another war of some type...either Germany verus the new Soviet Union under Stalin in the late 1920s would have easily occurred. Or we might have seen a war between Italy and Germany at some point. The interesting thing here is that the mighty test for the US would not have occurred, and we would have been still viewed as a second player in world politics. Japan would have still be a waiting episode in the 1930s for the US to prepare for...and would have likely been the "big" war to demonstrate US might.
FDR and Churchill allowed Russia to annex eastern Europe. Another forty odd years of enslavement for Poland, Romania, etc. That's a mark of shame.
